Hi Max,
Great job by you to provide us all these interesting information on the www.
I have just installed the dual booth with the standard rom (as secundary booth) and Resurrection as first (Love that rom!!!)
But I have a question about my apps which I had installed in the primary booth.
When I choose recovery it wipes the Resurrection and when I choose Back Up it ask me if
I want to back up to the external SD.
Is there a possibility to get my apps to Ressurection from the Standard Rom

Thank you in advance and best regards,

Might be an issue with gapps, some roms you have to flash gapps otherwise the buttons won’t work.

Hey Max how do you suggest that i try out a new ROM while keeping the data in the ROM i’m already using? ie: Without backing up or restoring

Max

Clone 1st rom to second then install.

Hi Max,

I have successfully dual booted by SG2,
Im using RR 3.0.6 as secondary rom and cMIUI 2.8.31 as primary rom.
but when i tried to install my Stock firmaware “XWLP7 india version” as primary rom,
Siyah aborted the installation saying “bad” (sorry, i dont remember the exact message).
What could be reason behind this?, can you please guide me about this,

Please suggest me the required steps to accomplish this as I want to use my stock firmware as primary rom.
I had flashed this stock firmware via Odin and it was working fine. But not able to flash it using CWM

Max

Stock ROMs can only be installed via ODIN, try installing it first then use Siyah to clone your stock rom to 2nd or use it as primary ROM.

Sorry for my bad English.
I have Samsung i9100 and according to the tutorial video i done everything.
I flashed the lasts Siyah kernel (5.0.1) and i moved my CM10 (4.1.2) to the second partition.
after this, i flashed on the primary partition the “RainBox” Rom and flashed the Siyah kernel for it too.
My status is :
i have on the primary and secondary partitions JellyBean Roms.
When i reboot my device The kernel let me choose what rom i want to load, this is not matter what load I’ve chosen ,my device shows me a Black screen and do NOTHING.

Please Help me with this.
Thank you & have a great day.

Hi Tamir,

Dont know abt dual boot, but i can give the suggestion to run rainbox rom on ur device,

have the rom what u had ie, CM10 in ur sd card ,
wipe the data in 2nd rom ,
wipe the data from main screen,
from CWM re install CM10,
then have the rainbox rom in ur sd card,
wipe the data again from main screen
install zip rainbox rom
NOW UR DEVICE WILL WORK

Tamir

Hi,
First, Thanks A lot.
I tried to install RainBox and CM10 One by one and both worked on my device.
Now i want to find a way to run them together on my device.

Thanks Anyway
